The work of preparing International Standards is normally carried out through ISO technic
13、al committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely wi
14、th the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft Intern
15、ational Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may b

19、rs, now covering various use cases ranging from emission-related diagnostics to vehicle-manufacturer-specific applications like calibration or electronic component software updates.With the introduction of new in-vehicle network communication technologies, the interface between the vehicles electron
20、ic control units and the external test equipment has been adapted several times to address the specific characteristics of each new network communication technology requiring optimized data link layer definitions and transport protocol developments in order to make the new in-vehicle networks usable
21、 for diagnostic communication.With increasing memory size of electronic control units, the demand to update this increasing amount of software and an increasing number of functions provided by these control units, technology of the connecting network and buses has been driven to a level of complexit
22、y and speed similar to computer networks. New applications (x-by-wire, infotainment) require high band-width and real-time networks (like FlexRay, MOST), which cannot be adapted to provide the direct interface to a vehicle. This requires gateways to route and convert messages between the in-vehicle
23、networks and the vehicle interface to external test equipment.The intent of ISO 13400 (all parts) is to describe a standardized vehicle interface which separates in-vehicle network technology from the external test equipment vehicle interface requirements to allow for a long-term stable external veh
24、icle communication interface, utilizes existing industry standards to define a long-term stable state-of-the-art communication standard usable for legislated diagnostic communication as well as for manufacturer-specific use cases, and can easily be adapted to new physical and data link layers, inclu
25、ding wired and wireless connections, by using existing adaptation layers.To achieve this, all parts of ISO 13400 are based on the Open Systems Interconnection (OSI) Basic Reference Model specified in ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers. When map

33、: Transport protocol and network layer services1 Scope1.1 This part of ISO 13400 specifies the requirements for diagnostic communication between external test equipment and vehicle electronic components using Internet Protocol (IP) as well as the transmission control protocol (TCP) and user datagram
34、 protocol (UDP). This includes the definition of vehicle gateway requirements (e.g. for integration into an existing computer network) and test equipment requirements (e.g. to detect and establish communication with a vehicle).1.2 This part of ISO 13400 specifies features that can be used to detect
35、a vehicle in a network and enable communication with the vehicle gateway as well as with its sub-components during the various vehicle states. These features are separated into two types: mandatory and optional.1.3 This part of ISO 13400 specifies the following mandatory features: vehicle network in
36、tegration (IP address assignment); vehicle announcement and vehicle discovery; vehicle basic status information retrieval (e.g. diagnostic power mode); connection establishment (e.g. concurrent communication attempts), connection maintenance and vehicle gateway control; data routing to and from the
37、vehicles sub-components; error handling (e.g. physical network disconnect).1.4 This part of ISO 13400 specifies the following optional features: DoIP entity status monitoring; DoIP entity firewall capabilities.2 Normative referencesThe following referenced documents are indispensable for the applica
